As answered by people managing RankingsFactor and Cert Decoder.
RankingsFactor's answer
RankingsFactor was created out of frustration with traditional SEO tools. Most platforms were either too expensive, too complicated, or too time-consuming for everyday marketers, bloggers, and small businesses. The founders saw a huge gap: people wanted quick, actionable insights instead of endless data overload.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
